My Thoughts on the Single...
Instinctive Love is a really good. But that's only to be expected from the great Katou Kazuki. The music is quite different from normal rock and pop, almost alternative, but it sounds like techno almost as well. Kazuki's voice really fits in well with the music, and the hooks and verses are really good. The chorus sounds cool as well. I have no clue what the song is about but it sounds good.
Melody on the other hand is more like a ballad. Kind of like Soba Ni Ite, but more upbeat. It sounds really nice, and the music is a nice contrast to his voice. The words are more smushed together and sung faster, which sounds really nice. And the guitar and drums that are masqueraded in there sounds good as well. Overall, the two songs are very good and it's very much worth giving them a listen. xD
